FREE RADICAL SCAVENGING ACTIVITY OF GYROCARPUS ASIATICUS BY USING DPPH AND ABTS METHOD

The antioxidant capacity of the barks of Gyrocarpusasiaticus belonging to the family Hernandiaceae was assessed by using ABTS (2, 2’-azino-bis (3-ethylbenzthiazoline -6sulphonic acid) andDPPH (2, 2-diphenyl-1-picrylhydrazyl) methods. The extract showed a very good antioxidant property which was compared with the standard Ascorbic acid in both methods. The IC50 of the extract was found to be 24µg/ml and 6µg/ml respectively which was compared with the standard Ascorbic acid which showed IC50 value of 16µg and 5µg in respective methods. It was concluded thatthat G.asiaticus showed a very good antioxidant activity and showed a better result in DPPH method compared to the other method.
